After John Shaw's welcome and introduction, several business issues were brought up.
The proceedings deviated somewhat from the agenda at this point. Task summaries and technical presentations were essentially given together. The proceedings are summarized below, on a Task by Task basis.
Task 1: Monitoring
John McLennan summarized the current status and the Sponsors indicated dates for receipt of reports and tools. A common theme associated with this and other presentations was strongly indicated by the Sponsors - some deliverables are available and they should be immediately provided to Sponsors for evaluation, even if they are only partially completed. There will be more discussion of this later in these minutes.
Paul van den Hoek brought up the issue of comprehending fracture initiation. There was no resolution as to how much initiation should be considered in the Task. The fracture models that had been inventoried and summarized were presented, as were models that would be still summarized. It was agreed that Cornell's model and FracPro would be added to the list and that field cases would be considered for the different models, where possible.
On a more generic level, Laurence Murray indicated that there should be a workshop on each Task.
It was indicated that the public domain model review would be sent out to everyone for review (this has been done) and that the Hall Plot summary would be provided soon (this has been done). Other review documents to be provided included a HIT summary (this has been done), a summary of friction calculation methods (this has been done) and a revised version of the "Best Practices" for SRT.
Task 2: Matrix Injection
The questions that were raised during David Davies presentation included specific issues about Injectivity Models?
Task 3: Soft Formations
The presentation was by Tony Settari. It was indicated that the completions spreadsheet would be discussed on Tuesday. Discussion of this was deferred, as was discussion of Llyod Barfoot's Problem Solving Spreadsheet. Tony Settari also suggested the following timelines. (Note that these deliverables and times have been superseded by those established in the breakout sessions on Wednesday, February 9.)
Task 4: Stimulation/Mitigation
David Davies presented the status of the stimulation/mitigation task. Discussion focused on molding the Task to determine:
Task 5: Layered Formations
This was presented by John McLennan. Several issues were presented and resolved.
Task 6: Horizontal Injectors
Tony Settari indicated status and the following commitments were made. (Note that these deliverables and times have been superseded by those established in the breakout sessions on Wednesday, February 9.)
Task 7: Database
Brian Odette demonstrated the database as it currently exists and showed his timetable with milestones. There was a request to provide further instructions on using the Newsgroups. This was provided and subsequently, instructions have been e-mailed to everyone.
Newsletter:
Ahmed Abou-Sayed described the three previous Newsletter issues and received commitments for articles, as shown in the Table below.

Tuesday February 8, 2000
Laurence Murray presented some of the highlights of the PEA-23 Project. As this information is central to this entire consortium effort PEA-23 will be summarized in detail, under separate cover.
After lunch, John McLennan presented some of the block testing that had been carried out in PEA-23.
John McLennan presented status and results of the Completions Selection spreadsheet formulated at the Soft Formations Workshop. Recommendations from Statoil and Marathon were presented. Jean-Louis Detienne presented a comprehensive selection of field cases that had been tested in the spreadsheet. Ahmed Abou-Sayed outlined the potential for attaching risk assessment and the statistics of failure. The comments from the Sponsors were that the spreadsheet should be developed in a stepwise fashion and that more details were required behind the spreadsheet. The resolution was that adding risk analysis should not be done without some form of proposal to the Sponsors. Adding certain statistics was favored by Laurence Murray. Christine Valvatne indicated that the spreadsheet formed a good vehicle for defining areas that we don't know enough about. Upcoming activity for finishing the spreadsheet was presented by John McLennan (modifying some fields, adding additional information to the cells, user manual).
Lloyd Barfoot summarized the status of the Problem Solving Spreadsheet and requested Sponsor input.
Wednesday, February 9, 2000
Sponsors met separately at the end of Tuesday's session. Their concerns and requirements were communicated to the Contractors, first thing on Wednesday morning. The Sponsors described the following issues.
After Laurence Murray expressed the Sponsors' concerns and the required actions by the Contractors, Benedicte Kvalheim and Knut Andersen summarized issues relevant to Brage, with particular emphasis on the layered character and required stimulation protocols.
There were breakout sessions between Contractors and Sponsors to address what needs to be accomplished in the upcoming months and to define the immediate required actions and deliverables for each Task. Afterwards, one representative from each breakout group presented the indicated course of action.
Task 1: Monitoring
The focus was arranging a workshop in conjunction with the Layered Formations Workshop and to promptly issue various products. Revised status for this and other Tasks was posted to the web site (under Task Status) on February 18.
Task 2: Matrix Injection
The results of the breakout session were presented. The immediate priorities included submitting the literature review, providing an interim report on the field data analyses and indicating to the Sponsors where there are gaps in information. Provide the model summaries (do not include obsolete or esoteric models). Plan for a Workshop in Edinburgh in May or June.
Task 3: Soft Formations
The results of the breakout session were presented by Jean-Louis Detienne. It is particularly desirable to process the available field data, in a fashion similar to what was done in PEA-23, to define the more sensitive parameters and the degree of loss of injectivity in soft formations. The basic considerations are "What is the Problem, How are we handling injection into soft formations today (existing tools), and What should be done in the future (technology gaps)?"
Task 4: Stimulation and Mitigation
The various milestones defined are shown on the PWRI web site (Task Status). These include a first draft of the literature review, establishing a deadline for the first draft of a synthesis of stimulation methodologies, incorporating surface facilities into the efforts and well testing. There was a presentation on economics by David Davies after lunch (see below).
Task 5: Layered Formations
The focus was arranging a workshop in conjunction with the Monitoring Workshop and to promptly issue various products. Revised status for this and other Tasks was posted to the web site (under Task Status) on February 18. Mark Tuckwood indicated that Bob Sydansk had several decades of specific experience in this speciality and would be willing to coordinate a workshop at Marathon's facility in Littleton, Colorado. Contractors were urged to expedite this and other workshops and to endeavor to hold them ASAP.
Task 6: Horizontal Wells
The results of the breakout session were presented. They were consolidated into a status page that has been posted to the web site.

Next Steering Committee Meeting
The issue of a date for the next Steering Committee meeting was brought up. It was agreed that the next meeting should be before the end of June 2000. It was suggested that it would be at the end or at some time during the Workshop Meetings at Heriot-Watt University in the week of May 29 through June 2.
Adjourn just before lunch.
Economics
Although some people had to leave, David Davies presented a conceptual plan for evaluating economics, after lunch on Wednesday. Paul van den Hoek agreed to make a Proposal on what might be done. Some of the questions and issues raised (in regard to economics) were:
